You can solve the problem with the global solution, but firstly I want to describe the solution for each project individually, cause of trustfully compatibility with most of Git clients and other implemented Git environments:
- Individual Solution
Go to the following location:
Local/repo/location/.git/
open "config" file there, and set your parameters like the example (add to the end of the file):
[user]
name = YOUR-NAME
email = YOUR-EMAIL-ADDRESS
- Global Solution
Open a command line and type:
git config --global user.email "YOU@EXAMPLE.COM"
git config --global user.name "YOUR NAME"
